To all whom it may concern:

Be it known that I, WILLIAM BELL LOWE, a citizen of the United States,residing at Marietta, in the county of Cobb and State of Georgia, haveinvented certain new and useful Improvements in Lubricating Devices; andI do declare the following-to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the figures of reference marked thereon,lwhich form a part of this specification.

My invention relates to lubricating devices, but more particularly to aforce-feed lubricator for journal-boxes7 and my invention has for itsobject to provide a device of this class which will elfectuallylubricate the shaft and journal-box with a minimum amount of oil andwith practically no waste of the same.

A further obj ect of my invention is to provide a lubricating devicewhich filters the oil after passing from the j ournal-boX and shaftbefore again being forced into the journal- A further object of myinvention is to provide a continuous lubricating device, as will behereinafter more fully described.

With these objects in view my invention consists in the novelconstruction of the forcefeed.

My invention further consists in the novel construction for leading theoil to the journal box and for returning the oil therefrom.-

My invention further consists in the novel construction of theBabbitt-metal lining for the journal-box.

My invention further consists in certain other novel features ofconstruction and in combinations of parts, which will be first fullydescribed and afterward specificallypointed out in the appended claims.

Referring to the accompanying drawings, Figure 1 is a vertical sectionalview taken through a j ournal-box constructed in accordance with myinvention. Fig. 2 is an end elevation of the same Fig. 3 is a verticaltransverse sectional view taken on line 3 8 of Fig. 1. Fig. 4 is avertical transverse sectional view taken on line 4 4 of Fig. 1. Fig. 5is a plan view of the lower section of the journalox, showing babbittlining and oil lubricator. Fig. 6 is an elevation of one of therollerdisks. Fig. 7 is a fragmentary sectional view taken on line 7 7 ofFig. 6. Fig. 8 is an elevation of one of the idler-disks.

Like numerals of reference indicate the same parts throughout theseveral figures, in which* v 1 indicates the journal-box, which iscomposed of the lower section 2 and an upper section 3, said sections 2and 3 being provided with flanges 4 and 5, through which flanges bolts 6pass to fasten the said two sections together, as shown in Fig. 8.Preferably located at the central point of the journal-box is anenlarged casing 7, as shown in Figs. 1 and 3. A chamber 8 is formed inthe lower section 2 of the journal-box.

9 Aindicates the stuffing-box, which is composed of the ring 10, formedin two sections 1l and 12, said sections being provided with flanges 13and 14 and bolted together with bolts 15, said ring l0`being providedwith vertical slots 16, through which'bolts 17 are adapted to pass tosecure said ring to the flanges 18 at each end of the vjournal-box- Thesaid ring 10 is provided with an annular concavity 19, as shown in Fig.1, and a port 20, located at the center of the lower section 12 of thering 10, leads from said annular concavity 19, as shown in Fig. 1.

Suitable packing material 21 is held in position by means of a ring 22,bolted to the said ring 10 by bolts 23, as shown in Fig. 2, said ring 22being constructed in two sections 23 and 24, said sections being securedtogether by bolts 25, which are bolted to the saidsections 23 and 24.This construction is duplicated at each end of the stufling-box, asshown in Fig. 1.

26 indicates the Babbitt metal lining, Which is composed of an uppersection 27 and a lower section 28, said babbitt extending from the endsofthe journal-box to the central casing 7 and chamber 8, as clearlyshown in Fig. 1.

29 indicates the 'cam force-feed-operating device, which is constructedin two sections 30 and 31, said sections being secured together by anysuitable means-as, for instance, by flanges 32, bolted together, Fig. 4.

Referring to Fig. l in connection with this cam, it will be seen thatthe same is provided with a centrally-located eccentric-rib. Said member29 being secured around the shaft 33 revolves therewith, as is obvious.

Referring to the chamber 8, (shown in Figs. 1 and 4,) it will be seenthat the mem IOO log

IIO

ber 29 extends within said chamber and revolves within the enlargedcovering 7.

Located within the chamber 8 is a cylinder 40, within which the piston41 operates.

42 indicates the piston-rod, which passes through a suitable box 43, anda cross-head 44 passes through said piston-rod near the outer' endthereof. A coil-spring 45 is located between the cap of the stuffing-box43 and the said cross-head 44. Formed on4 the outer end of the saidpiston-rod or connected thereto is a fork 46, designed to hold a singleroller 47, said roller being located directly under the eccentric-rib 34and designed to be in contact therewith.

Referring to Fig. 4, it will be seen that two said casting 49 beingbolted to said flange 51, l

as shown in Figs. 1 and 4.

Referring particularly to Fig. 5, 52 indicates filter-screens, which arecomposed of a series of layers of screens of different meshes, saidlayers being bolted together by bolts 53 and said screens being located,as shown, between the partitions 5() of the casting 49.

Referring again to Fig. 1, it will be seen that the cylinder' 40 isprovided with a lug 54, which is threaded into the bottom of the chamber8, and extending into the said cylinder 40 at the lowest point thereofare ports 55, said ports carrying a valve 56, and said ports are coupledby means of a couplingsleeve 57 to a nipple 57 at the bottom of the feedoil-pipe 58.

Locatedin the cylinder 40, as shown in Figs. 1 and 4, are ports 59,which are provided with valves 60, said ports entering the chamber 8, asclearly shown in Fig. 4.

Entering chamber 8 above the filtering- .Screens 52 are the returnoilways 61, said oilways leading from the concavity 19 in the ring 1()of the stuffing-box 9, as clearly shown in Fig. 1.

Referring to the Babbitt-metal lining 27, and in this connectionreferring to Fig. 5, it will be/seen that the feed-oilways 58 enterthesaid babbitt Alining at 62, and leading from the point 62transversely are two grooves 63, said grooves gradually tapering, asshown. Intersecting said transverse grooves 63 are two longitudinalgrooves 64,

(shown also in dotted lines) in the upper section of the babbitt lining,said grooves 66 leading to the concavity 19 in the ring 10 of thestuffing-box 9 and also leading to the chamber 8 in the center of thejournal-box, as shown in Fig..5.

Referring to Fig. 6, which shows one of the roller-disks 67, it will beseen that the same is composed of two sections 68 and 69, securedtogether by bolts 70. A series of groups of rollers 71 are carried inthe disk 67, said rollers being provided with large bores 72 and held inthe disk by means of pins 73, as shown in Fig. 7, said rollers extendingbeyond the face of the disk, as shown.

Referring to Fig. 8, which illustrates one of the idler-disks 74, itwill be seen that said disk is composed of two sections 75 and 76,secured together by bolts 77. As shown in Fig. 1 a roller-disk 67 isinterposed between two idler-disks 74 on each side of the cam 29, saiddisks acting as a thrust-bearing and reducing friction to a minimum.

Having thus described the several parts of my invention. its operationis as follows: The cam member 29 being Secured around the shaft 33revolves therewith, and the roller 47, carried by the piston-rod 42, isheld in contact with the eccentric-rib 34 by means of the coilspring 45.As said shaft revolves the eccentric-rib 34 forces the piston down intothe cylinder 40, oil having first been poured into the chamber 8. On theupstroke of the piston 41 the intaking-valves 60, Fig. 4, are opened andthe oil is drawn from the charnber 8 into the cylinder 40. On thedownstroke of the piston said intaking-valves are closed and the outletor feed valves 56, Fig. 1, are opened and the oil is forced from thecylinder into the feed-oilways 58 and up into the babbitt lining, saidoil passing into said lining at 62, Fig. 5. The shaft 33, revolvingwithin the babbitt lining takes up the oil, and the force of the pistondistributes the oil within the transverse groove 63, from whence it isforced into the longitudinal groove 64, the rounded corners 65 of thegrooves 63 being for the purpose of facilitating the flow of the oilfrom the grooves 63 into the longitudinal grooves 64. As shown, theoil-grooves taper in depth and width toward the ends thereof, so that aless quantity of oil is required to fill the grooves near the ends thanis required where the oil enters the grooves, thereby insuring an evendistribution of the oil along the babbitt lining. 4A portion of the oil,however, is forced transversely along the grooves 63 to the point 80,which point connects with the oblique grooves 66 in the upper section ofthe babbitt lining. Thus the shaft 33 is lubricated the entire length ofthe journal-box, the longitudinal grooves 64 extendingthe length of thejournal-box and terminating-in the concavity 19 in the ring 10 of thestufIing-box 9, the inner ends of said IOO ' is again drawn into thecylinder 40 and forced` above the filtering-screens 53.

oblique grooves in the' upper section of the babbitt lining alsoterminate in the concavity 19 in the ring 10 of the stufling-box 9 andalso in the chamber 8. by the shaft 33 only a suflicient quantity isheld thereby to properly lubricate the same, and the continuous influxof the oil into the babbitt lining forces the superfluous oil into theconcavity 1 9 in the ring 1() of the stufiingbox 9 and also into theoil-chamber 8. The oil entering the said concavity 19 passes out throughthe port 2O into the return-oilway- 61, Where it is again 'led into thechamber 8 The oil passing from the babbitt lining directly into theoil-chamber passes down between the cam member 29, a sufficient quantitythereofbeing taken up by the disks to properly lubricate the same, theexcess of oil passing into the oil-chamber 8' and into thefilteringscreens 53, Where it is deprived of all dust and impuritiesWhich it may have taken up during its passage along the babbitt lining,and after passing through the filtering-screens it intothe feed-oilways58, again passing up to the shaft 38, Where it is again used forlubricating. Thus it is seen that absolutelynone of the oil is Wastedand only a sufficient quantity of the oil is consumed to properlylubricate the shaft and babbitt.

Having thus described my invention, I do not Wish to be understood aslimiting myself to the exact construction herein set forth, as variousslight changes may be made therein which Would fall Within the limit andscope of my invention, and I consider myself clearly entitled to allsuch changes and modifications.
